LP/Vinyl Convert to WAV File
A friend wants to convert some rare LPs to his computer for making WAV
files. He has a Creative Labs Audigy 2 Audio Card. His turntable is connected to the phono-in jack of his receiver, via two RCA connectors. His PC has Windows XP and CoolEdit Pro installed. He has two output options on the receiver: (1) HEADPHONE JACK - He could use this with an adapter to go into the 3.5" mini connector on the Audigy 2 Sound Card's Line Input. (2) TAPE OUTPUT - He could also use a Y splitter cable with stereo RCA jacks that terminates into a 3.5" mini, and plug it into the Audigy 2. __________________________________________________ _________ (a) Which one of the above two is preferred and are they both Line Level Outputs? (b) Does the HEADPHONE output represent a pure line out, or is it equalized for a Headphone? |

The HEADPHONE output is typically taken from the power amplifier output, via a series resistor which lowers its amplitude. It's affected by the setting of the volume, balance, bass and treble controls, and its level would have to be manually adjusted to line-level standards via a voltmeter. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |

His turntable is connected to the phono-in jack of his receiver, via two RCA connectors. His PC has Windows XP and CoolEdit Pro installed. So far, so good. He has two output options on the receiver: (1) HEADPHONE JACK - He could use this with an adapter to go into the 3.5" mini connector on the Audigy 2 Sound Card's Line Input. Second choice. Reason: Level goes up/down with receiver volume control, affected by tone/"loudness" controls. Quite likely more noisy because it is attenuated output from the power amp. (2) TAPE OUTPUT - He could also use a Y splitter cable with stereo RCA jacks that terminates into a 3.5" mini, and plug it into the Audigy 2. Prefect choice (for this situation, at least.) (a) Which one of the above two is preferred and are they both Line Level Outputs? "Tape Out" is preferred. Recording is obvously the intended use of this output. (b) Does the HEADPHONE output represent a pure line out, or is it equalized for a Headphone? It will do in a pinch, but certainly to be avoided if you have a real "Tape Out" available. There is typically no difference between the headphone output and the speaker output except some attenuation on the headphone output (to keep you from hearing how noisy the power amp really is.) Headphone output *may* be the same as line-level depending on many variables most significantly, the setting of the volume control. |

The pros sometimes run their Line Level is a bit hotter than the domestic version :-) This is probably sensible. Domestic equipment rarely comes equipped with output and input trim controls. It's much safer to run outputs a little low (and need to turn the power amp up a bit) than to run them hot and risk overload. For some reason, domestic CD players often have particularly hot Line Outs. I wonder if the audiophile criticism of digital audio being "harsh" is caused by a CD player overloading their "Line" input? |

With the possible exception of the TAPE OUT, but likely not enough difference to be of concern in the Real World(TM). Perhaps that was the unstated assumption by Mr. Bear. except the phono input. Which if a completely 'nuther subject. Not line-level (consumer or pro), or mic-level (or EQ) either. |

With the possible exception of the TAPE OUT, but likely not enough difference to be of concern in the Real World(TM). Perhaps that was the unstated assumption by Mr. Bear. Indeed. Trying to adapt pro standards to consumer gear is fraught with difficulty. As you are aware - consumer line level is indeed lower voltage than pro but certainly within the range of compatability for practical purposes. Much pro gear has -10dBV 'compatabilty' as a switched option or a gain setting, although consumer line outs seem to vary hugely in reality, especially now with low voltage operation of some portable devices. You can always fix it with a gain trim anyway. Graham |

I wonder if the audiophile criticism of digital audio being "harsh" is caused by a CD player overloading their "Line" input? That was certainly the case in the early days of CD. Pre-CD, the commonly accepted "line level" standard was 1 volt peak-to-peak. When CDs came into use, CD player designs settled on a 2 volt peak-to-peak full-scale standard. There were some older pre-CD preamps and receivers which overloaded and clopped pretty badly when fed a 2-volt signal, and some rather nasty sound was the result. This _should_ be a thing of the past, with modern designs... but it's certainly possible that some newer designs are still overloading at the higher CD voltages. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
